Abstract

The utility model discloses a multi-point air distribution hot blast stove with full forward combustion and full reverse combustion. The hot blast stove comprises a stove body, wherein an upper combustion chamber and a lower combustion chamber are respectively formed in the stove body; an upper grate and a lower grate are respectively arranged at the bottoms of the upper combustion chamber and the lower combustion chamber in the stove body; a funnel-shaped fuel bin of which the upper part is integrated with the inner wall of the stove body and the lower part is necked as a cylinder is arranged in the upper combustion chamber; the lower port of the funnel-shaped fuel bin is positioned on the upper grate; a cylindrical smoke and fire channel of which the lower end is open is longitudinally arranged in the center of the funnel-shaped fuel bin; an annular upper air channel is formed between the outer wall of the lower part of the funnel-shaped fuel bin and the inner wall of the stove body; and a plurality of air inlet holes are uniformly formed on the outer wall of the cylinder on the lower part of the funnel-shaped fuel bin. By using the hot blast stove, a combustible can perform secondary full combustion in the lower combustion chamber to form forward combustion, so that the aims of reducing dust and environment friendliness are fulfilled; and therefore, the optimum effects of energy conservation, emission reduction and extremely high thermal efficiency are achieved.

Description

The clean-burning hot-blast stove of the positive and negative burning of multiple spot air distribution
Technical field
The utility model relates to a kind of hot-blast stove, particularly relates to a kind of clean-burning hot-blast stove of the various solid-state combustibles positive and negative burning of clean-burning multiple spot air distribution that is used for.
Background technology
At present, in various small-sized stove and accessorys, much used solid-state combustible is fully burnt; Cause heat production low, pollute greatly, wasted a lot of low-calorie fuel, institute pollutes in order to prevent to burn; Have to use moulded coal or anthracite, limited fuel source, increased the heat production cost; Many solid-state combustibles not only can not utilized, become the rubbish of contaminated environment on the contrary.
Summary of the invention
The purpose of the utility model is exactly for overcoming defective and the deficiency that above-mentioned prior art exists, and a kind of sufficient combustion, quantity of heat production are big, the clean-burning hot-blast stove of the positive and negative burning of multiple spot air distribution of fuel saving and provide.
The technical scheme that adopts is:
The clean-burning hot-blast stove of the positive and negative burning of multiple spot air distribution comprises body of heater, is respectively equipped with upper combustion chamber and lower combustion chamber in the described body of heater; The bottom that is positioned at upper combustion chamber and lower combustion chamber in the body of heater is respectively equipped with upper furnace grate and lower fire grate; The below of lower fire grate is a dedusting chamber, and the body of heater of lower fire grate below is provided with shoot door, and the body of heater between described upper furnace grate and the lower fire grate is provided with outlet flue; The outlet flue place is connected with flue; It is characterized in that being provided with top in the described upper combustion chamber and inboard wall of furnace body is an one, the bottom necking down is the funnel-form Bunker of cylinder, and the lower port of funnel-form Bunker is positioned on the upper furnace grate; The center of funnel-form Bunker vertically is provided with the cylindric fireworks channel of lower ending opening; Be formed with annular upper air duct between the outer wall of described funnel-form Bunker bottom and the inwall of body of heater, evenly offer a plurality of fresh air inlets on the outer wall of funnel-form Bunker bottom cylinder, offer an air inlet that is connected with annular passage on the outer wall of body of heater at least; The air inlet place is connected with air duct, is provided with adjusting valve in the air duct.
The utility model compared with prior art has the following advantages:
1, the hot-blast stove of the utility model can adapt to the abundant burning of various solid-state combustibles, thereby has fuel source widely.
2, the utility model once insert more solid fuel, thereby burning time is long, saving of labor, laborsaving because the top in body of heater is provided with bigger funnel-form Bunker.
3, the utility model has been offered a plurality of fresh air inlets on the outer wall of funnel-form Bunker bottom, and fuel wind through upper air duct in upper combustion chamber carries out burn incompletely one time, makes and forms carbon dioxide and carbon mono oxide mixture in the upper combustion chamber; Because the top of upper combustion chamber is shutoff; Thereby anti-the burning downwards of the gaseous mixture that makes generation fully burnt through upper furnace grate entering lower combustion chamber, and simultaneously, unburnt combustible falls into lower fire grate; Combustible carries out secondary and fully burns in lower combustion chamber; Form and just to burn, thereby realized the purpose of depositing dust, environmental protection, and then realized energy-conservation, reduction of discharging, the high optimum efficiency of the thermal efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
The clean-burning hot-blast stove of the positive and negative burning of multiple spot air distribution comprises body of heater 1, is respectively equipped with upper combustion chamber 2 and lower combustion chamber 3 in the body of heater 1; The bottom that is positioned at upper combustion chamber 2 and lower combustion chamber 3 in the body of heater 1 is respectively equipped with upper furnace grate 4 and lower fire grate 5; The below of lower fire grate 5 is a dedusting chamber 6, and the body of heater 1 of lower fire grate 5 belows is provided with shoot door 7, and the body of heater 1 between upper furnace grate 4 and the lower fire grate 5 is provided with outlet flue 8; Outlet flue 8 places are connected with flue 9; Being provided with top and inboard wall of furnace body in the upper combustion chamber 2 is one, and the bottom necking down is the funnel-form Bunker 10 of cylinder, and the lower port of funnel-form Bunker 10 is positioned on the upper furnace grate 4; The center of funnel-form Bunker 10 vertically is provided with the cylindric fireworks channel 11 of lower ending opening; Be formed with annular upper air duct 12 between the outer wall of funnel-form Bunker 10 bottoms and the inwall of body of heater 1, evenly offer a plurality of fresh air inlets 13 on the outer wall of funnel-form Bunker 10 bottom cylinders, offer two air inlets that are connected with annular passage 14 on the outer wall of body of heater 1; Air inlet 14 places are connected with air duct 15, are provided with adjusting valve 16 in the air duct.
